Contrast
It is to adjust monitor window contrast. The larger the number, the higher the contrast
is. You can use this function when the whole video bright is OK but the contrast is not
proper. Note that the video may become hazy if the value is too low. If this value is
too high, the dark section may lack brightness while the bright section may over
exposure.
The value ranges from 0 to 100. The recommended value ranges from 40 to 60. The
default value is 50.
Saturation
It is to adjust monitor window saturation. The larger the number, the strong the color
is. This value has no effect on the general brightness of the whole video. The video
color may become too strong if the value is too high. For the grey part of the video,
the distortion may occur if the white balance is not accurate. Note that the video may
not be attractive if the value is too low.
The value ranges from 0 to 100. The recommended value ranges from 40 to 60. The
default value is 50.
Sharpness
The value here is to adjust the edge of the video. The larger the value is, the clear
the edge is and vice versa. Note that there is noise if the value here is too high.
The value ranges from 0 to 100. The recommended value ranges from 40 to 60. The
default value is 50.
Gamma
The value here is to adjust the gamma value of the video.
The value ranges from 0 to 100. The recommended value ranges from 40 to 60. The
default value is 50.
Mirror
It is to switch video left and right limit.
This function is disabled by default.
Image rotation
The function can be used to change the direction of video surveillance image. It can
select 0,90,180,270 degree.
Note:
90 and 270 degree : only for 1080P(1920x1080), 1.3M(1280x960), 720P(1280x720),
VGA(640x480), 640x360, QVGA(320x240)
EIS (Electronic
Image
Stabilization)
It can realize electronic anti-flicker function via comparison algorithm of image
difference, which can effectively solve the problem of image jittering during
application and it can make the image clearer.
